C. difficile GDH & Tox A/B

Introducing the C. difficile GDH and
Tox A/B Combi Cassette

For the rapid chromatographic immunoassay for the qualitative detection of Clostridium difficile
Glutamate Dehydrogenase (GDH), Toxin A and Toxin B in the human faecal specimen.

What is the Test?

The C. difficile GDH & Tox A/B Combi Cassette simultaneously detects three distinct antigens
in faecal specimens for C. difficile; GDH, Toxin A and Toxin B.

*Tests are professional use only under clinical settings.

What is the Disease?

  • Clostridium difficile is an opportunistic anaerobic
    bacterium that can grow in the intestine once normal flora has been altered by antibiotics.
  • Toxigenic strains of C. difficile can cause infection (Clostridium difficile infection – CDI) through the
    production of two toxins; Toxin A (tissue-damaging enterotoxin) and/or Toxin B (cytotoxin).


  • I can present as a spectrum of symptoms; ranging from asymptomatic carriage or mild diarrhoea, to potentially life-threatening pseudomembranous colitis.
Mortality/Morbidity – Clinical Implications
  • The organism is spread via oral-faecal route, acquired from infected individuals both directly and indirectly.
  • Due to its contagious abilities C. difficile poses a real threat to healthcare environments (large concentration of
    at-risk individuals – immunocompromised/undertaking antibiotic treatment), so rapid detection is paramount to prevent spread.


Why use C. difficile GDH and Tox A/B Combi Cassette?

  • The C. difficile GDH and Tox A/B Combi Cassette allows for the rapid and accurate detection of C. difficile, with test results available after 10 minutes.
  • The ability to conduct simultaneous GDH/Tox A&B testing coupled with rapid provision of results allows for Clostridium difficile infections to be managed more effectively.

Key Features

  • Complete system, no additional reagents required. 
  • Simple and easy to use.
  • Rapid result offered within 10 – 20 minutes.
  • In-built procedural control.
  • Can be used with both solid and liquid faecal specimens.
  • Ability to rapidly identify C. difficile is key for patient care.
